Answer:
This is for the offspring to show traits that come from both the mother and father.
Explanation:
Gametes are formed by a kind of cell division called meiosis in which the chromosome number is halved. Thus the said gamete cell is said to contain a haploid number of chromosomes.
The fusion of two haploid gametes is called fertilization. It results in the formation of single celled zygote which has a diploid number of chromosomes. The zygote now divides and develops to produce the offsprings whose somatic cells are diploid.
The answer is kwashiorkor. Kwashiorkor, also known as “edematous malnutrition” because of its relationship with edema is a nutritional disorder most often seen in regions experiencing famine. It is a form of malnutrition caused by an absence of protein in the diet.
Mutations give rise to variability
Giraffes' necks got longer over time
Traits can be passed from parent to offspring
Accumulated changes in an individual are passed on to its offspring
All species evolve over time
Accumulated changes in an individual are passed on to its offspring is the argument of Lamarck's theory of evolution which was incorrect and is option D.
Wisemen discarded the above-mentioned statement and gave the concept of germ cells and somatic cells. Also, he conducted an experiment in which he removed the tails of rats for 22 continuous generations, but it was noticed that the rats of the 23rd generation were still born with a tail.
This proved that the changes were occurring in somatic cells which are not responsible for changes in the offspring. The actual changes in the offspring are due to mutations occurring in the germ cells, so Lamarck's theory was discarded.

Answer:
Enzymes are proteins that act as catalysts for reactions, such as those in cellular respiration. They increase the likelihood of a reaction by lowering the energy required for a reaction to occur. In the process, enzymes are left unchanged by the reaction. ... The resulting molecules from the reaction are called products.

paracrine signaling
endocrine signaling
direct signaling across gap junctions
Answer:
The correct answer is the third option - endocrine signaling.
Explanation:
The endocrine signaling takes place when endocrine cell organs or glands release hormones that flow through the bloodstream and that act on distantly located target cells in the body. The endocrine system includes several glands that release or secretes different hormones.
The pituitary gland transfers signals to other endocrine glands to release or inhibit their hormone production according to the brain signals. The adrenocorticotropic hormone (ACTH) is released by the anterior pituitary gland that stimulates cortisol release in the adrenal glands in stressed conditions.
Thus, the correct answer is option third - endocrine signaling.
The pituitary gland secreting hormones is an example of endocrine signaling, where hormones are secreted directly into the bloodstream and carried to target cells.
The secretion of hormones by the pituitary gland is an example of endocrine signaling. Endocrine signaling refers to the process where glands secrete hormones directly into the bloodstream, which are then carried to the target cells elsewhere in the body. In contrast, autocrine signaling involves cells responding to their own signals, paracrine signaling refers to cells communicating with nearby cells, and direct signaling across gap junctions involves communication between adjacent cells through specific channels.
